Expression must evaluate to node set in Xpath error while trying to get value

I am getting error while trying to get nodes which has value of Home and Auto. Any help is appreciated.

XElement coverage = vehicle.XPathSelectElement("s0:VehicleCoverage/s0:Coverages/[CoverageLimitName=('Auto' |'Home')]", namespaceManager);

I like to fetch nodes under 

<Coverages>
  <Coverage>
    <CoverageLimitName>Home</CoverageLimitName>
    <OptionalCode1>WY</OptionalCode1>
    <OptionalCode2>Bodily Injury</OptionalCode2>
    </CoverageLimitValue>
    <Premium>166.00</Premium>
  </Coverage>
  <Coverage>
    <CoverageLimitName>Auto</CoverageLimitName>
    <CoverageLimitValue>
      <OptionalCode1>T</OptionalCode1>
      <OptionalCode2>Property Damage</OptionalCode2>
    </CoverageLimitValue>
    <Premium>88.00</Premium>
  </Coverage>
  <Coverage>
  </Coverage>
  ....
  </Coverage>
</Coverages>

I would like to use xpath only and would like to fetch entire coverage tag when it has CoverageLimitName as home and auto

My educated guess is that you want the following:

/s0:VehicleCoverage/s0:Coverages/s0:Coverage[s0:CoverageLimitName = 'Auto' or s0:CoverageLimitName = 'Home']

Which, for the document you show, would return both Coverage elements. (Given that the namespaces are properly dealt with.)

We have to guess because your sample XML document lacks a namespace declaration and because you did not tell us what exactly you are looking for.
